With the comfortable Seidel operator-software through the serial interface of a PC
Direct operation by means of two keys on the servo amplifier and a 3-character LED
display for status display in case of no PC available
Fully programmable via RS232 interface
Power supply :
All shielding connections directly on the amplifier
Output stage : IGBT- module with isolated current measurement
Regen circuit :
DC-link voltage 300 — 900 V DC, can be paralleled
Digital current controller (space vector pulse-width modulation, 62.5 µs)
Freely programmable digital speed controller (250 µs)
Integral position controller with adaptation possibilities for customer needs (250 µs)
Pulse direction interface integrated for connection of a servomotor to a stepping- motor
control
Evaluation of the resolver signals or sine-cosine signals of a high-resolution encoder
Encoder emulation (incremental ROD 426-compatible or SSI)
Adjustable setpoint ramps
2 analog monitor outputs
4 programmable digital inputs (normally, two are defined as limit-switch inputs)
2 programmable digital outputs
Freely programmable combinations of all digital signals
Safe electrical separation to EN 50178 between the power input / motor connections and
the signal electronics, provided by appropriate insulation/creepage distances and complete
electrical isolation
Soft-start, overvoltage recognition, short-circuit protection, phase-failure monitoring
Temperature monitoring of servo amplifier and motor
(when using motors from the 6SM series with our pre-assembled cables)
0 2 . 9 9
B6 rectifier bridge, directly off 3-phase earthed supply
system, integral power input filter and inrush circuit
with dynamic distribution of the regen power between
several amplifiers on the same DC-link circuit
internal regen resistor as standard, external regen
resistors if required
